  1. 3An aeroplane has a stall speed of 100 kt. At what speed will it stall in a level, co-ordinated turn with a load factor of 1.5?

    Show the answer

    Answer C. The stall speed increases with the square root of the load factor. In a co-ordinated turn at a load factor of 1.5, the aeroplane stalls at 100 × √1.5 = 100 × 1.225 = 122 kt. Multiplying by the load factor itself (150 kt) or by √2 (141 kt) are the classic mistakes.
